You will need to hack squid. The basic thing to do would be to have a
static internal object that is the gif file (a la the icons), and in the
client side code use that storeentry where the current miss detection
occurs. To retrieve the other url, you need to have a routine that will
read the entire thing via the store (which will load the object into the
cache).

You can do this very easily in 2.6/3.0, or with a little less ease in
2.5
